Additional information
The documentation for the respective module includes additional information on parameter
assignment of I/O modules.
4.2.3 Diagnostics information using the web server
System diagnostics using the CPU Web server
The CPUs of the SIMATIC series have an integrated Web server and let you display the
system diagnostics information by means of PROFINET. Any terminal devices, such as PCs
or smartphones, can thus access module data, user program data and diagnostics data of a
CPU by using an Internet browser. This means access to CPUs is possible without installed
STEP 7.
In addition to normal websites, the Web server provides so-called basic websites with
reduced content that are adapted to the requirements of small screens with low resolution.
Using CPU 1516-3 PN/DP as an example, the following figure shows the start page of the
Web server:
